Default IFR for 28 vs 26

I have a 2000 holden caprice with ls1 and a 26.6 injectors and a 98 camero with 28.8 injectors ,and comparing the IFR tables (using LS1_EDITOR) of the 2 cars I found that the 28.8 table starts more than the 26 but after 60Kpa the value ot the 26 becams more than the 28.8 .
any one have any Idea why?

Good question. I assume that you are sure that both cars have a stock IFR table loaded?
I went from 26.6 to 28.8 pound injectors and just multipled the table by 1.08271 and then fine tuned from there. I can't imagine why the 26ers would flow more above 60kpa?
